SPSS17.0 and Clementine12.0 were applied to the frequency analysis,association analysis as well as cluster analysis.Results Relevant 294 literature were selected. The involved 174 Chinese drugs selected from the 294 literature are divided into 19 major groups and 39 minor groups. The top three herbs categories were tonifying medicinal,heat-clearing medicinal and blood-activating and stasis-resolving medicinal. And of which the leading five drugs that were mostly used are Poria cocos,Acorus gramineus,Ginseng,Angelica sinensis and Radix Rehmanniae Praearata. The association analysis revealed that Radaix Rehmanniae Praeparata and Fructus were the most relevant among all the selected drugs.
